Suiffet.說(shuō)：“由于改造及時(shí)，應(yīng)用了正確的診斷系統(tǒng)，維護(hù)成本大大減少?！? 艾默生拉丁美洲總裁Leo Rodriguez說(shuō)：“Petrobras小組的成就對(duì)于該廠是非常具有價(jià)值的，也是工程專家和技術(shù)的一個(gè)可能性案例。通過(guò)他們的創(chuàng)新，計(jì)劃組由艾默生幫助已將PlantWeb數(shù)字技術(shù)用到了卓越的操作和成功生產(chǎn)之上。” Petrobras Zarate應(yīng)用的是基金會(huì)現(xiàn)場(chǎng)總線通信技術(shù)，與艾默生的DeltaV數(shù)字系統(tǒng)，Rosemount®流量?jī)x、水平和溫度儀表，Micro Motion®科里奧利流量計(jì)和Fisher®閥門(mén)一起構(gòu)成一個(gè)網(wǎng)絡(luò)。 高級(jí)控制工具可以提高產(chǎn)品質(zhì)量和性能。例如，在DeltaV系統(tǒng)中神經(jīng)網(wǎng)絡(luò)軟件的應(yīng)用，可使在反應(yīng)器中的質(zhì)量預(yù)測(cè)更有效，并且Petrobras Zarate可在工廠中精確到某一個(gè)產(chǎn)品。來(lái)自AMS Suite的預(yù)測(cè)診斷，包括將信息傳遞至運(yùn)營(yíng)的智能設(shè)備管理器和現(xiàn)場(chǎng)設(shè)備快速?zèng)Q定的維護(hù)人員。 PlantWeb架構(gòu)是一個(gè)開(kāi)放式的，基于標(biāo)準(zhǔn)的數(shù)字自動(dòng)化解決方案，與智能現(xiàn)場(chǎng)設(shè)備、數(shù)字系統(tǒng)、控制過(guò)程軟件、管理設(shè)備和其它資產(chǎn)系統(tǒng)構(gòu)成網(wǎng)絡(luò)，為工廠管理提供信息，包括預(yù)測(cè)未發(fā)生的事情和避免生產(chǎn)中斷和停產(chǎn)的校正行為。 [FONT=times] original text [/FONT] [font=times][Color=#708090]Austin, Texas （April 16, 2008） – Emerson Process Management today announced production gains and reduced plant downtime through a multi-year digital automation project at Petrobras Zarate, a polystyrene manufacturing facility 80 kilometers north of Buenos Aires, Argentina. Through the modernization, production rose by 3 to 5 percent — to 66,000 tons per year. The plant‘s availability is now 99 percent and product reliability is up by 2 to 3 percent. The plant, which produces high impact, general purpose crystal and bioriented sheet polystyrene, is part of Petrobras Energia, an integrated energy company in Buenos Aires. Polystyrene is a lightweight plastic used to make items such as disposable food containers and cutlery, footwear, school materials, and parts used in refrigerators, air conditioners and vacuum cleaners. As Petrobras Zarate‘s process automation supplier, Emerson provided consulting, staff training, and installation of its PlantWeb® digital architecture, AMS® Suite asset management software, and DeltaV™ automation system. The project modernized the plant‘s high impact and crystal polystyrene facilities, including the water, steam and air utilities and the reactor operations. Polystyrene production at Petrobras Zarate had been limited by a 1980s-era distributed control system. "We needed modernization to place the plant in the vanguard of technology and ensure it could respond to the needs of the market," said Roberto Gorbaran, instrumentation supervisor at Petrobras. Plant managers had several goals in mind when they decided to partner with Emerson for the technology upgrade. "We discussed a migration strategy towards a control system that could give us greater reliability, would fall within our budget, would comply with medium- and long-term strategy and satisfy management and the business," said Adolfo Suiffet, maintenance manager at Petrobras Zarate. The transformation to digital was implemented in stages between 2002 and 2005. Petrobras Zarate saved $1.13 million in 2005 when, with Emerson‘s assistance and aided by its digital valve and instrument technology, plant personnel completed the final hot cutover of operations control to the DeltaV system without stopping production. Annual plant stoppages have been reduced by half, to once every two years, because plant staff can now make decisions based on more reliable data about their operations. "Thanks to being able to intervene at the right moment, with the right diagnosis, maintenance costs have been cut. " said Suiffet. "The accomplishments of the Petrobras team are highly valuable to the plant and a great example of the results possible through engineering expertise and technology," said Leo Rodriguez, president of Emerson Latin America. "Through their innovation, the plant team assisted by Emerson has used PlantWeb digital technology for operational excellence and manufacturing success." The Petrobras Zarate plant uses FOUNDATION fieldbus communications to network Emerson‘s DeltaV digital systems, Rosemount® flow, level and temperature instruments, Micro Motion® Coriolis flowmeters and Fisher® valves with Fisher FIELDVUE® digital valve controllers. Advanced control tools increase production quality and capacity. For example, application of neural network software in the DeltaV system made quality prediction in the reactors more effective, and Petrobras Zarate was able to up rates for certain products in the plant. Predictive diagnostics from AMS Suite: Intelligent Device Manager deliver information to operations and maintenance personnel for fast decisions on field devices. PlantWeb architecture is an open, standards-based digital automation solution that networks intelligent field devices, digital systems, and software to control processes and manage equipment and other assets. It delivers information for facilities management, including predictive alerts of pending malfunctions and guidance for corrective action to avoid production interruptions and shut downs.[/color][/font]
